To specify a transfer ready size for a SCSI write command, follow these steps:
Step 6
switch(san-ext-nport)#
stop command-id 100
Stops the command with the specified ID.
switch(san-ext-nport)#
stop all
Stops all outstanding commands.
Step 7
switch(san-ext-nport)#
clear counters
Clears the counters associated with this N
port.
Step 8
